The compact KM2774 module enables direct connection of up to four AC motors with reversal of rotation direction and a further travel function. For each motor, three mutually locked Triac outputs with 230 V AC and up to 1.5 A are available. The outputs are protected against overload. An adjustable overcurrent limit protects the motor from damage. The typical control signals can be wired via 24 V inputs. Status and error messages are available via the fieldbus and via LED at the module.
